Limits and SizesInstagram's help page "Use hashtags on Instagram" says: you can use up to 5 tags on a post, and if you include more than 5 tags on a single photo or video, your comment will not post. Many older articles say 30; that is the older rule. Always trust the app and the current help page.
What this means for your posts
Choose the few tags that match your post best. Our three-layer method works well within a small number: one broad tag, one or two specific tags and one of your own.
Other rules on the same page
- Numbers are allowed in hashtags. Spaces and special characters such as $ or % will not work.
- You can only tag your own posts.
- Posts from private profiles do not show on public hashtag pages.

Questions people ask
Why do other sites say 30?
That was an earlier Instagram limit. The help page we read on the date above says up to 5, so we show that.
Do hashtags in the first comment count?
The help page says tags can be added in the caption or in comments and that the limit applies to a post; check the app if you use comments.
